You are developing a Windows Presentation Foundation (WPF) application that displays financial data.
The following style is applied to every Label control that displays currency. (Line numbers are included for reference only.)

You need to ensure that the style is updated to meet the following requirements regarding currency:
Which markup segment should you insert at line 06?

• A. It must display the number with the regional currency settings.
• B. It must be right-aligned.

You develop a Windows Presentation Foundation (WPF) application. This application is
used to output data trends to customer service representatives.
A data trend analysis is performed in a function named UpdateTrendData. The trend
analysis is a long-running process.
The application contains the following code segment.
Class MainWindow
Private Sub UpdateData(By Val arg As Object) Dim data As Double = UpdateTrendData()
... End Sub
End Class
UpdateData is currently invoked on the UI thread when the form is first displayed.
You need to process the data in a manner that does not cause the UI to freeze.
What should you do?

• A. Use Me.Dispatcher.BeginInvoke to invoke UpdateData passing in the priority of Normal.
• B. Use ThreadPool.QueueUserWorkltem to invoke UpdateData.
• C. Use ThreadPool.SetMaxThreads(2,2) and invoke UpdateData.
• D. Use Me.Dispatcher.BeginInvoke to invoke UpdateData passing in the priority of Background.
